What is a normal D-dimer level?

A normal D-dimer is considered less than 0.50. A positive D-dimer is 0.50 or greater. Since this is a screening test, a positive D-Dimer is a positive screen. [4][5][6][7] There is not necessarily a critical level for a D-dimer.

What does a high D-dimer lab mean?

An elevated D-dimer level is not normal. It’s usually found after a clot has formed and is in the process of breaking down. If you are having significant formation and breakdown of blood clot in your body, your D-dimer may be elevated. A negative D-dimer test means that a blood clot is highly unlikely.

What raised D-dimer levels?

Elevated levels may be seen in conditions in which fibrin is formed and then broken down, such as recent surgery, trauma, infection, heart attack, and some cancers or conditions in which fibrin is not cleared normally, such as liver disease.

What is a positive D-dimer?

A positive D-dimer result may indicate the presence of an abnormally high level of fibrin degradation products. It indicates that there may be significant blood clot (thrombus) formation and breakdown in the body, but it does not tell the location or cause.

What does a positive D-dimer mean?

What can elevate D dimer?

D-dimer level may be elevated in any medical condition where clots form. D-dimer level is elevated in trauma, recent surgery, hemorrhage, cancer, and sepsis. [104] Many of these conditions are associated with higher risk for deep venous thrombosis (DVT).

What does high D dimer levels mean?

A high D-dimer means that he has had some inflammation or breakdown of blood clots. In terms of whether this is significant, then his doctor will look at his clinical symptoms, not just the blood tests.
